"The Dark Lord will rise again, Crouch! Throw us into Azkaban; we will wait! He will rise again and will come for us, he will reward us beyond any of his other supporters! We alone were faithful! We alone tried to find him!"

Etymology

The name 'Lestrange' echoes the French phrase l'étrange, literally "the strange one", refering to Bellatrix's mental disability. In Old French, estrange means "foreigner"[5]. The surname may allude to English journalist Roger L'Estrange, who was known for opposing religious toleration and for being involved in plots against the government of William and Mary, similar to the Lestranges' intolerance about blood purity and involvement in the Death Eaters organisation.
